5 Signs Your Ductless Unit May Need Repairs

April 17, 2021

Ductless systems, like every other machine, can malfunction over time. Keeping an eye out for warning signs and repairing them before harm happens will help you protect your HVAC system. The following are signs that your ductless unit in Clear Spring, MD, may need repairs.


The air handler in your system uses oiled bearings to minimize friction on the motor while it’s running. As these bearings wear out, friction increases, resulting in a noisy grinding sound when you operate them.

If you hear this sound, call for service as soon as possible. Otherwise, the air handler could overheat and flame out.

Reduction in Cooling Output

If you can’t feel cool air anymore, your refrigerant may be leaking. After all of the liquid drains from the system, it’ll only act as a fan. Refrigerant leaks slowly over time, resulting in a gradual loss of cooling energy.

Malfunctioned Controls

If your ductless unit doesn’t turn on or off even after you’ve tested the batteries in your remote and tried to turn the system on manually, there’s most likely an electrical problem. Alternatively, a professional may need to replace the reversing valve.

High Electrical Bills

The average lifetime of your ductless unit is 12 to 15 years. With time, HVAC systems lose efficiency. High energy consumption in a newer device may indicate anything from a clogged air filter or dirty equipment to short-cycling or failing components.

Ice Formation on Evaporator Coils

The evaporator coils will freeze over if the airflow reduces. This may result from a clogged air filter, faulty thermostat, refrigerant leak, broken fan or dirty coil. If you ignore this, the cooling coil could warp due to the ice’s weight, necessitating a full coil replacement.
